Silva said the homeowner, whose name has not been released, was with his wife in their guest house when they heard a commotion outside. A man, who was later identified as Shepherd, had climbed over a fence into the couple's yard and was trying to break into the guest house.

Silva said the homeowner grabbed a gun and fired two shots at Shepherd, wounding him in the arm and leg. Shepherd then crawled beneath the homeowner's parked pickup.

When officers arrived, Silva said, they took Shepherd into custody without incident. He was taken to Memorial Hermann Northwest Hospital. His condition was not released, but Silva said he is expected to survive.
